Arts and crafts comprise a whole host of activities and hobbies related to making things with one's own hands and skills. Crafts are divided into handicrafts or "traditional crafts" (doing things the old way) and the rest. Some crafts have been taught and practiced for centuries, while others are modern inventions, or popularizations of crafts originally practiced in a very small geographic area. Most crafts require a combination of skill, speed and patience; most crafts on a beginner’s level however are capable of being taught to anyone. Many community centers and schools run evening or day classes and workshops offering to teach basic craft skills in a short period. Many of these crafts become extremely popular for brief periods (a few months, or a few years), spreading rapidly among the crafting population as everyone emulates the first examples.
